Of the 6 kingdoms of life, which 2 are prokaryotic?

Eubacteria & Archaebacteria

2

Cell theory

1) All living things are composed of one or more cells
2) The cell is the smallest functional unit of life
3) All cells come from pre-existing cells

3

Cell structure

1) Plasma membrane
2) DNA region (nucleus)
3) Cytoplasm

4

This significance of cell (plasma) membrane function

*Diffusion
*osmosis
*facilitated transport
*active transport
*endocytosis and exocytosis

5

What are endocytosis & exocytosis?

Mass movement of materials into/out of cells

6

What are considered passive transport?

Diffusion, Osmosis, facilitated transport

7

What are considered active transport?

Active transport, Endocytosis, exocytosis

8

What are cell organelles

*Nucleus
*endoplasmic reticulum
*ribosomes
*golgi bodies
*vesicles
*mitochondria

9

What is the nucleus

Headquarters, it will govern what the cell will do

10

What is osmosis

The diffusion of water

11

What is facilitated transport

It needs the help of a protein to get across

12

What is active transport

It costs energy to go against the concentration gradient

13

What are the 3 stages of aerobic respiration

1) Glycolysis (in cytoplasm) 2 ATPs
2) Short prep steps & citric acid cycle 2 ATPs
3) Electron transport chain (taking the byproducts of the first 2 stages 32 ATPs
A typical total of 36 ATP's
